 fourth joint, like in jyrophaena . but also the fifth very email, the fol- 

 lowing middle and next-last Joints (c-lO) increasingly strongly trans- 

 verse, at least t\Nice as broad as long. Fronotum about three times as broad 

 as long, posteriorly almost as broad as elytra, narrowing anteriorly with 

 rounded sides, almost rightangular hind corners and very finely bounded 

 posterior margin, at middle convex; the elytra scarcely longer than pro- 

 notum, broadest posteriorly and with almost even posterior margin; abdom- 

 en broad, with rounded sides, dorsally concave, with high side-mergins, 

 ventral side ovate convex. The ability of Gyrophaena to curve abdomen 

 upward and forward, is in Encephalus . by the ..peculiar structure of abdomen, 

 so strongly developed, that this can bend entirely forward closing over the 

 forebody, whereby the ventral side is upward. In this position the follov»ing 

 species acqires more likeness with a small, round Ajathidium than with a 

 Staphylinid. 



In Middle and North Europe only one species occur which also is found in 

 our country.

In combination with the above described characters easily identified by
